What about the frequency? I've bought all mine used and they are running 700 frequency. Is it better to run them lower for longevity or is it more consistent?
These are underclocked on purpose - they pull less power at lower frequency. If I pumped it up to 700, it'd just be another S7 and i'd have to put the back fan back on and move it to my warehouse. The S7s in my warehouse get around 1th/s more - but to me that's not really enough to worry about undoing the mods Sidehack did to these. |

Out of curiosity, have you noticed a difference in hash rate versus temp at all? Mine are running at 59-60-59 degrees after some room manipulation. I wondered if it ever really mattered so long as it didn't overheat and shut down over 80. My next step is routing this ducting into the office area and shutting off the heaters. Right now they are venting into a cold warehouse.
Here's a snapshot of now, which is pretty much average for these S7s: https://i.imgur.com/tjKfxts.pngI keep the AC in my office to 60F, and the miner causes it to get up to 64 or so. For the rest of my farm, I keep them venting into an open warehouse just like you do. I haven't seen too much difference in hashrate as long as they're not running at shutdown temps. |

This pool has the best community. I have one of Sidehack's hacked S7s (which used to be in Fuzzy's mine) running in my office again - at least another 3th/s to the pool! Running in one of phillipma's silencer boxes. https://i.imgur.com/kcA07t3.jpgYikes! What temp are those boards at with that box? 60c is the current chip temp, but they can get up to 70 or so. Interesting. You must have a good airflow setup. I would have thought that box would be trapping a ton of heat. Had a typo - its 69c up to 74. The box has two openings, so airflow is fine. Here's the back: https://i.imgur.com/i2HjjcC.jpgSidehack's S7s have different PIC controllers and are undervolted, only taking up 900w, so you just need one fan at like 25%. |

Running in one of phillipma's silencer boxes. https://i.imgur.com/kcA07t3.jpgI haven't seen one of these silencer boxes. Does it actually kill out some of the noise? Must be nice to mine at work. Welcome back (if you ever left). I joined up with one S9 4 or so days ago. Glad to see the blocks popping, and I'd like to think I brought a little luck with me  This community has been very active so far and I love getting insight from other miners. Not too many in my area here in Arkansas. Never left - just didn't have this one machine running. The box drops noises from 55 db to 25db when i wrap it in a moving blanket. Sidehack's S7s draw like 900watts though, so not too loud anyway. |

Yes, this is a fun little toy.
RIP to the BM1384 product development - onto newer chips!

Where could I find my ramp up status, sorry for my question  Goto the Shift Graph under Workers |

I could use some help for converting BTC to BCH
I'd like to see if I can convert some BTC to BCH and get one of the S9's to add a little more hashing power to my units.
The steps are pretty straight forward. Find an address that has both BTC and BCH from before the fork. Move the BTC from that address to another one. Export the private key of the now empty BTC address and import it into a BCH wallet. |

Not exactly... 16 days is the 5Nd and is 5 times network diff, so we expect to hit 5 Blocks in 16 days @current diff if pool hashrate stays steady and luck holds at 100%... Mine on!  Cool, thanks man. So, today is 15th, and this month has 31 days. We have exactly 5Nd left. We stay 100% lucky, we'll find 5 blocks right before Feb. And on 31st, how many of those 5 blocks will be paid to the miners by then? Haha, sorry man. Whatever happens, happens. Mine on! You get paid for every block we hit based on the number of shares you have over the last 5 network diffs. I'm going to use made up numbers for the hashrate, but they'll give you an idea. At 100% luck, the pool should find a block in about 2.2 trillion shares (the network difficulty is 2.2 trillion.) 5 ND is 10.10 trillion shares. When we hit a block, the pool code looks at the number of shares you had in the last 10.10 trillion of them, and compares that to the pool hashrate. If you were mining for 7 days, and had 100 million shares, your payment would be whatever portion of those last 10.10 trillion shares were yours. However, the full 10.10 trillion share took place over 2 weeks, so for 7 days you weren't contributing. We'd say you were half way into your ramp up period. Once you've been mining for about 2 weeks, when you look back at the last 5ND shares, you'll always see your total amount. That's when you're fully ramped up. Does that clear it up? |

Hello Kano,
When are we going to get back the held payouts?
Thank you
Nobody reads anymore. This is just a matter of trust. i sure Kano reads. and i am waiting for his reply. Kano has said multiple times that he's building a new accounting/payout module. This will let you get paid out your dust a specific time, either weekly or monthly. |

O my guys, I only started mining on the 10th, and we have found 4 blocks. Still ramping up, but love to see it, thanks all. Can anyone suggest a mobile app for monitoring or even a website that is mobile friendly?
I use the VH ckpool iPhone app - it is great. |

Only parameters being submitted to node/server is time, nonce and extranonce2.
I dont' think modifying merkel root is allowed. If mining software modifies merkel root, how server going to validate it against the parameters I'm submitting ?
The server can modify it, if it wants. I don't believe that ckpool does. I was just explaining how the mining space is infinite. |

2. Does cgminer takes that into consideration when pointed to solo.ckpool ?
...
5. Maximum nonce on 32 bit is 4294967295. That's ~4.2 Gh/s. When you have more hashing rate than this does what mining software (cgminer in particular) does in meantime its waiting for next work ?
2. Accepted shares can be a lower difficulty than the network diff, and just show you (and the mining software) that it's working 5. You can change the time, or the extra nonce. You can also get fancy with adjusting the merkle root. Mining space is practically unlimited. |

Nicehash doesn't send standard data back to your miner. The found blocks is likely not really you finding blocks.
It's not that they don't send standard data, it's that it's usually not Bitcoin that people are doing rentals for and they don't send special data for that (and even if they did, the miner wouldn't understand it). Finding a block of CoinX with a diff of 1M is essentially the same data to/from the miner as a Bitcoin block at the current diff. A valid block is a valid block, it's just an issue of a valid block of what and at what diff it's valid. You're right, but also I'm not sure what event happens to trigger the "Found Block" counter in the miner interface to go up. It can get a false positive when a multipool switches coins - not even that you found a share higher than the network difficulty, just Nicehash switching the coin on you. |

How to increase the mining difficulty on an Antminer s9?
On nicehash my miner has a difficulty of 65.5k and has 4 blocks in less than a week (great luck that's why I'm wanting solo)
But on Solo.ckpool my miner only has a difficulty of 12.5-12.7k and doesn't get nearly the same performance (less/not as good shares)
I know it all has to do with luck, but having a miner find 4 blocks within a week and only owning it for 2 weeks there's gotta be something to get better performance when solo.

As far as clock speeds and voltages, how would warranty work then? An unlocked product without warranty?
That could be a possibility if you could easily swap out hash-boards. Basically there would be a warranty on the controller and so on but not the unlocked hash-board?
I would say changing the voltage outside some parameters would void the warranty. I love the idea of swappable hashboards and a 3U form factor. I don't anyone moved away from the server form, I think it was more efficient to pack more hashpower in a smaller form factor, both from the air cooling aspect as well as fitting more machines in smaller spaces. While the common wisdom is that miners are made to run in data centers, I think the reality is that they're made to run in air cooled warehouses (and not temperature controlled data centers) moreso. The shoebox form factor fits that much better than data center rack concept. |

Configurable voltages! The ability to adjust the frequency of a board chips and it's timings.
If I want to feed my miner 1500w, even though it only needs 1200w, it should be able to be clocked higher.
Better thermodynamics - the 100ish chips per board w/heat sinks and a high static pressure fan works in the current shoebox form factor, but why not other form factors?
